This chapter describes the general characteristics of the basic
oscillation of Fig. 4-1 (page. 19). Contact Murata for detailed
characteristics of oscillation with specific kinds of ICs and LSIs.
Fig. 5-1 shows examples of actual measurements for stability
of the oscillation frequency.
The stability versus temperature change is ±0.1 to 0.5% within
a range of -20 to +80°C, although varies slightly depending on
the ceramic material.
Influence of load capacitance (C
frequency is relatively high, as seen in formula (4-1) (P.20).
It varies approximately ±0.05% for a capacitance deviation of
±10%. The stability versus supply voltage is normally within
±0.05% in the working voltage range, although it varies with
the characteristics of the IC.
